Method and apparatus for transferring carbonaceous material layer

Abstract

In a method and apparatus for transferring carbonaceous material layer, a carbonaceous material layer is grown on a growth substrate, and a first continuous conveying unit is used to feed the growth substrate and a transfer material, so that a gluing layer of the transfer material is attached to the carbonaceous material layer on the growth substrate. Then, a transformation device changes a viscosity of the gluing layer for the latter to adhere to the carbonaceous material layer. A second continuous conveying unit is further used to transfer and then separate the mutually adhered transfer material and growth substrate from each other, so that some part of the carbonaceous material layer is transferred onto the gluing layer while other part of the carbonaceous material layer remains on the growth substrate. Thus, at least a one-layer-thickness of the carbonaceous material layer is transferred.
